The former Scelionidae (sensu stricto) is considered to be a part of Platygastridae, recently. During the parasitic wasp collecting with yellow pan trap, aiming at investigating promising biological control agents which attack on plantbug pests for soybean cultivation, one new species and one unrecorded scelionine species were identified. Opisthacantha albertoi sp. n. was collected from central part of korean peninsula. It is very unique by its yellowish body, compared with the black of the most recorded korean scelonine species. It has a long ovipositor which is 1.3 times longer than body length. It was named after the late Dr. S.-B. Ahn, the noctuid specialist. The unrecorded Tiphodytes gerriphagus (Marchal) was famous for its extremely extraordinary habit of diving for Hymenoptera to attack the eggs of gerrid hosts (Gerris, Trepobates spp.). It was collected nationwidely in Korea. As a result, two genera are newly added in korean scelionine fauna and korean Scelioninae is composed of eight species in five genera in total.
Lysiphlebia japonica (Ashm.) was determined as a dominant and a keystone aphid parasitoid in the ecosystems and agro-ecosystems of Korea. Host range of the parasitoid is reviewed on grounds of original and published records and it is discussed in relation to integrated pest management.
Mikhail A. Kozlov Zoological Institute, Russian Academy of Sciences, St. Petersburg A new species, Fusicornia koreica sp. n., from Korea is described and illustrated. This species is distinguished from F. indica of India and the key for discrimination is presented. This is the first record of the genus in the Palaearctic region.

Two Proteleas species, P. nefrensKononova and P. sulcatus Kozlov, are recorded for the first time in Korea. Teleasinae, which includes these two Proteleas wasps, is also a newly-recorded subfamily in Korea.
The purpose of this study was to provide basic data on dementia care center, define them in terms of the therapeutic environment, and to find improvements by developing and applying the therapeutic environment assessment tool for the dementia care center. Based on government policy data on national responsibility system for dementia and dementia care center, prior researches of the elderly with dementia, and analyses on the prior therapeutic environment assessment tools for dementia elderly facilities, in this study, the dementia care center was divided into 10 spaces and 8 therapeutic space indicators were developed to evaluate the therapeutic environment of the dementia care center. Using the tools, the assessment was conducted by visiting 4 dementia care centers in Seoul from August 4 to 12, 2020. As a result of the assessment, some differences are confirmed. 1) Difference between centers due to location, size, building type, and surrounding environment. 2) By space, "office", "cafe", "toilet", "external space" and "corridor" were lower than average. 3) Therapeutic space indicators lower than average were ‘cognitive and orientation support', ‘accessibility', and ‘continuity of function'. Therefore, plans for cognitive and intellectual support, practical application of universal design, and space layout considering continuity of function should be reflected in the plan in the operation of dementia care centers that will increase in the future.
Riptortus pedestris (Hemiptera: Alydidae) is known to occur in barley field during spring. But, it is unlikely that R. pedestris can find host resource to reproduce in the spring season. To test this hypothesis, we assessed the reproduction of R. pedestris population collected from field from March to September. Riptortus pedestris were collected at intervals of three days from 15th of each month. Females of R. pedestris collected from trap were provided with just water in a breeding dish, and eggs laid were collected daily. Quality of R. pedestris eggs at each month was also evaluated by providing them as host resource to two egg parasitoids. The collected eggs were divided into three groups and tested for hatchability and parasitism by two egg parasitoids, respectively. As a result, R. pedestris population collected in March and April did not reproduce, and fecundity and proportion of reproduced females were the highest in August. But, neither hatchability nor parasitism rate of R. pedestris eggs show significant difference among the sampling months. In conclusion, R. pedestris starts to reproduce from May, and fecundity reaches highest on August. No change in egg quality was found among the study periods.
Geographic clines in genetic polymorphisms are widely believed as an evidence of climate change. We hypothesized green peach aphid, Myzus persicae Sulzer, one of the major insect pests in highland chinese cabbage cultivation, may also have some interactions with climate change. As the first step, we tried to find the available markers from six local strains (five collected at different heights in Hoengseong and Pyeongchang area and one from laboratory). A strain from Jeju island was used as an out-group. Although there was no significant difference in sequences of partial ribosomal RNA fragment and mitochondrial cytochrome oxidase I, and esterase isozyme pattern, we found four inter-simple sequence repeat (ISSR) markers in 22 used ISSR primers (+AGA, +CCA, +CGA, CGA+). These primers can be used as good markers to trace the M. persicae gene flow because they showed specific bands according to local strains.
The green peach aphid, Myzus persicae (Sulzer), is one of the most serious pest in cabbage cultivation. Field survey was carried out to know the insecticide resistance levels in five main cabbage cultivation regions (Pyeong-chang, Hong-cheon, Bong-wha, Mu-ju and Je-ju) in 2009. The green peach aphid can resist a wide range of insecticides in five surveyed local populations. Among the nine tested insecticides, four chemicals (methomyl, bifenthrin, pymetrozine and flonicarmid) showed less than 50% mortality in the recommended concentration in all populations. Multi resistant (MR) strain was selected from these populations and esterase over-expression, modified AChE (MACE) and mutation(s) in para-type sodium channel were analysed using native IEF and quantitative sequencing with five local populations. Esterase over-expression and MACE (StoF mutation) were observed in all populations including MR strain. LtoF mutation is well known as a kdr mutation in para-type sodium channel. However, even though LC50 values of MR strain noted over 2,000 times higher than that of susceptible strain against bifenthrin, any mutation was not detected in para type sodium channel and also local populations. These results suggested that unusual case could be existed in pyrethroid resistance mechanism in green peach aphid.
Diamondback moth (DBM, Plutella xylostella L.), the most destructive pest of cruciferous crops, is well-known as typical subtropical insect pest. A number of biological agents such as diseases, parasites and predators can affect populations of DBM in the fields negatively. In previous reports, we suggested Cotesia glomerata, Diadegma semiclusum, and Microplitis plutellae as promising natural enemies to DBM control at highland areas, but these species are larval parasitoids. In 2004~2009, we searched highland fields cultivating various cruciferous crops for PUPAL parasitoids which can supplement the unsatisfactory parasitism in the augmentative release of larval parasitoids. We obtained adults of hymenopteran parasitoid from DBM pupae in early July at Hoengseong region (asl 540 m), and then identified as Diadromus sp., although being a critical species so far. This parasitoid showed high rate of parasitism, about 13.2%, in mid October at the same region. Development period from oviposition to emergence of Diadromus sp. ranged from 14 to 18 days under 23℃ condition. Adult longevity, > three weeks, was longer when it was provided with 10% sugar solution as food than with water only or without food. Male adults mated as soon as emerging from parasitized DBM pupae, and laid eggs into DBM pupae for a week. Parasitism by Diadromus sp. was highest on 7th day after emergence. In contrast, lethality of DBM pupae which were not parasitized by wasps showed 60% on average for seven days. Parasitized DBM pupae could be stored at 10℃ for two weeks. The simultaneous augmentative release of larval parasitoids and pupal parasitoids can be an important component to integrated DBM management program in the future.
